The Art Production Fund honored artistic duo Elmgreen & Dragset and designer Miuccia Prada on Monday, at the eatery that once housed the Four Seasons restaurant.

Gary Simmons created temporary tattoos of disco balls for the event, which had a “Bright Lights, Big City” theme, was hosted by Casey Fremont, co-hosted by Yvonne Force Villareal and Doreen Remen, and produced by Bettina Prentice.

“Orange Is the New Black” star Alysia Reiner announced that Tuesday would be a “snow day,” which prompted the crowd to stay late and sip more Dom.
